An apparatus including at least one processor; and at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to: determine a channel bandwidth; and based upon the determined channel bandwidth, determine a maximum power reduction for the channel bandwidth using a value of the channel bandwidth as a value in an equation.

Apparatus and method using different optimum maximum power reduction values linearly dependent on different bandwidth groups

A technique for power control including receiving, by a user device, a resource block allocation for uplink transmission that includes one or more resource blocks within a frequency channel; determining at least one resource allocation region or which an uplink resource block allocation within the resource allocation region will require an additional maximum power reduction (e.g., to reduce interference to a protected frequency band); and applying, by the user device, the additional maximum power reduction for a transmission power of the user device based on the resource block allocation being within the at least one resource allocation region.

Additional maximum power reduction for uplink transmission for wireless networks

A technique for power control including receiving, by a user device, a resource block allocation for uplink transmission that includes one or more resource blocks within a frequency channel; determining at least one resource allocation region for which an uplink resource block allocation within the resource allocation region will require an additional maximum power reduction (e.g., to reduce interference to a protected frequency band); and applying, by the user device, the additional maximum power reduction for a transmission power of the user device based on the resource block allocation being within the at least one resource allocation region.

A technique includes controlling uplink transmission power of auser device, wherein a resource block allocation for the user device includes resource blocks in a user device channel bandwidth that is a part of a base station channel bandwidth and the user device channel bandwidth is less than the base station channel bandwidth, wherein the controlling uplink transmission power of the user device comprises reducing a maximum transmission power of the user device for an uplink transmission via the resource block allocation by a maximum power reduction value that is determined based on a distance of the resource block allocation from at least one edge of the base station channel bandwidth.

Maximum power reduction for uplink bandwidth part for wireless networks

There is provided applying minimum radio frequency performance requirements to uplink transmission, when there are multiple possible multiple sets of minimum radio frequency performance requirements. A network node determines a condition for applying a first set of minimum radio frequency performance requirements or a second set for minimum radio frequency performance requirements by a device for uplink transmissions in a given radio technology. The network node transmits an indication to the device indicating whether the first set or the second set of requirements can be applied for subsequent uplink transmissions.

Applying minimum radio frequency performance requirements to uplink transmissions

A method and apparatus for allocating quasi-contiguous uplink data resources for a user device is provided. Transmission of data comprise at least two data clusters of sub carriers expanding over gaps reserved for uplink control channel in order, for example, to mitigate transmission power reductions due to multi-cluster transmission.
